I have a S&S Aircraft propeller. SER.S.1889
SS-SS.210
I have no idea about what plane this came off what year it is or what it may be worth. The guy that sold it to my mom told her it was from a gipsy moth training plane but I dont think S&S made them but I could be wrong. The propeller is in good shape.
If someone can help me figure out more about this prop it would be great.
